82 MILTON Or dim suffusion veiled. Yet not the more Cease I to wander where the Muses hannt Clear spring, or shady grove, or sunny hill, Smit with the love of sacred song ; but chief Thee, Sion, and the flowery brooks beneath.. That wash thy hallowed feet, and warbling flow, Nightly I visit: nor sometimes forget Those other two equalled with me in fate., So were I equalled with them in renown, Blind Thamyris and blind Maeonldes, And Tiresias and PMneus, prophets old : Then feed on thoughts that voluntary move Harmonious numbers ; as the wakeful bird Sings darkling, and^ in shadiest covert Md? Tunes her nocturnal note. Thus with the year Seasons return; but not to me returns Day, or the sweet approach of even or morn Or sight of vernal bloom, or summer's rose, Or flocks, or herds, or human face divine ; But cloud instead and ever-during dark Surrounds me? from the cheerful ways of men Cut off, andj for the book of knowledge fair, Presented with a universal blank Of Nature's works, to me expunged and rased, And wisdom at one entrance quite shut out. So much the rather thou, Celestial Light, Shine inward, and the mind through all her powers Irradiate ; there plant eyes ; all mist from thence Purge and disperse^ that I may see and tell Of things invisible to mortal sight.
